NHT-3DL broadband electromagnetic radiation analyzer

With the freezing of the fifth generation communication technology (5G) standard, 5G is gradually moving towards commercialization. At the same time, the new European "2013/35/EU Directive" has also strictly limited the electromagnetic field risks that may be generated around electronic devices, which puts higher requirements on the safety detection of electromagnetic radiation environment. The NTH-3DL broadband electromagnetic radiation analyzer is the latest electromagnetic radiation detection equipment launched by Italian company MICRORAD with reference to the 2013/35/EU Directive and electromagnetic environment control related standards. It can achieve full range detection of high and low frequencies (DC~100GHz), and has a complete FFT analysis module and a signal analysis module with complete oscilloscope triggering and marking functions. It has manual high-precision triggering function and amplitude or time marking function. Function. The FFT module enables NHT-3DL to achieve complete frequency selective analysis function in the low-frequency domain (DC~1MHz), with complete time-domain and frequency-domain analysis functions, which can quickly and accurately present and store instantaneous or pulse waveforms; In broadband operating mode, NTH-3DL can quickly demodulate and reconstruct pulse radar signals, accurately and quickly analyze various types of pulse signals in complex environments (response time less than 500nS), and has automatic measurement functions for Tau, PRF, and duty cycle, perfectly meeting the detection needs of the field of electromagnetic radiation safety.
The NTH-3DL broadband electromagnetic radiation analyzer is a complete, reliable, and traceable electromagnetic radiation safety monitoring system. As a pioneer in the field of electromagnetics, MICRORAD has accumulated multiple leading patented technologies through years of research and accumulation, which are fully reflected in NTH-3DL MICRORAD provides NTH-3DL with a range of patented high-performance probes in various specifications, covering a large frequency range from low to high frequency microwaves (DC~100GHz). By equipping different types of probes, you can easily achieve precise measurement of electric field, magnetic field strength, magnetic induction strength, and power density in various complex environments. The host and probe are plug and play (automatic identification and calibration), and you no longer need to carry multiple instruments. Simply replace different probes on site to easily achieve accurate measurement of NMR machines, power systems, induction furnaces, welding systems, broadcast antennas, or wireless systems in all directions. MICRORAD company strictly calibrates each probe according to the International Commission on Non Ionizing Radiation Protection standards and national standards before leaving the factory, which makes NHT-3D unparalleled in accuracy and practicality. Compared to NHT-310, which only has a full range broadband measurement function, low-frequency electromagnetic wave signals are more complex and easier to interfere with, while NTH-3DL has low-frequency (DC~1MHz) FFT/spectrum analysis function, which will greatly help measurement personnel to conduct more accurate and effective analysis in this field.
NHT-3DL integrates the latest technologies and manufacturing processes in the field of electromagnetic environmental safety. It is powerful yet easy to operate, and its launch is a revolutionary solution in the field of electromagnetic radiation environmental safety assessment. The equipment has good anti-interference performance and is not easily affected by the measurement site. The control keys on the host panel are designed with laminated buttons, and various commonly used functions are displayed in shortcut keys, which is very suitable for on-site use. The high-definition LCD display of the host can display detailed information including measurement values and working status in real time. With control keys, it is easy to switch between real-time values and spatial averages, select measurement units, and set alarm values. Even under harsh operating conditions, it can ensure easy and accurate control of the device and display various display results in a concise and clear manner. At the same time, through the host fiber port (optional) or wireless module (optional, automatic measurement value compensation deduction function), you can easily control and set the device in real time through your mobile phone and tablet. We provide a fully functional mobile and tablet app application, which allows you to achieve complete and seamless operation on your mobile phone or tablet, and remotely view the device's working status in real time. and conduct data collection, etc, Eliminate the hassle of cable connections.
